Well it could be the pump itself going bad or a short in the wiring, possible clogged fuel filter. There is a valve what looks like a tier valve cap on the fuel rail if you can get you hands on a pressure gauge and hook it up, you should see the pressure increase and decrease, if it does not start looking elsewhere.

SOURCE: 1998 Dodge Neon engine died when valves started knocking and car will not restart.

Check the engine for compression. Your head gasket may be shot. I have a 97 that had a similar problem, and we did the head gasket, car runs fine now. Prior to doing the gasket mine wouldn't start at all.

Do a compression test.

I seen this before first of all don't let the car dealer to BS the way to your money, most of the time is noting wrong whit the sensor it self but is the plug than goes in to the sensor this what i recommend is to buy another sensor from your local auto part store or salvage yard (cheaper) get three pieces of cable and solder directly in to the sensor brake the plastic around the sensor plug if necessary and secure the three cables to it put some silicon in between the solder and the place the new sensor on top of the old one so you now wish wire goes to which and cut and attach one by one. I now this works 100% i have done it my self many times if you need diagrams or sensor locations you can find that at www.alldatadiy.com now if you still have problems unplug all harness especially all the ones than comes from the back of the engine because that engine tends to leak oil on top of the harness if you have wires doing shortcut replace that section you can solder use heat string tube and change the insulation hose they sale those on part stores to put some zip tides on the ends and you will have your car back and will last Note don't let it get to close to the exhaust use zip tides to keep from touching hot areas.

While your car is running.......pop the hood and find the throttle body. The throttle body is where your air filter tube/hose goes to the engine. Locate the throttle position sensor which should be on the side of the metal throttle body. This should be the item causing this. If you grab the plug that is on the sensor and wiggle it while the car is running then the engine should rev and act up if thats the problem. If not let me know and I can direct you further. Thanks.
